  hi guys:

  we are having Q.921 DLPI problem when trying to establish ISDN layer 2 connection with the E1 switch of the telecom carrier, the carrier switch is unable to establish layer 2 link with our * server with a quad E1 card, 

  Here is a trace provided by telecom.

  U   -> N     DL_RELEASE_IND 

  U   <-  N    (PRA_PROTOCOL_CONFIG) 

  U    <- N    DL_ESTABLISH_REQ 

  look like this DL_RELEASE_IND is part of Q.921, but i don't see this in libPRI, is the LIBPRI implementation missing the DLPI part of the Q.921? I also found some free code of Q.921 Q931 on the net, Linux and FreeBSD seams also contains this DLPI in their isdn drivers.

  reading the libpri code, it tells it is doing the ua only, no DLPI, shall we add DLPI or we can tell teleco to only use ua layer 2 link establishment?

  Any hint of help is greatly appreciated.

  Matt
